pop3d::udb(n) Tcl POP3 Server Package pop3d::udb(n) __________________________________________________________________________________________________________________________________________________ NAME
pop3d::udb - Simple user database for pop3d SYNOPSIS
package require Tcl 8.2 package require pop3d::udb ?1.0.1? ::pop3d::udb::new ?dbName? dbName option ?arg arg ...? dbName destroy dbName add user pwd storage dbName remove user dbName rename user newName dbName lookup user dbName exists user dbName who dbName save ?file? dbName read file _________________________________________________________________ DESCRIPTION
The package pop3d::udb provides simple in memory databases which can be used in conjunction with the pop3 server core provided by the pack- age pop3d. The databases will use the names of users as keys and associates passwords and storage references with them. Objects created by this package can be directly used in the authentication callback of pop3 servers following the same interface as servers created by the package pop3d. ::pop3d::udb::new ?dbName? This command creates a new database object with an associated global Tcl command whose name is dbName. The command dbName may be used to invoke various operations on the database. It has the following general form: dbName option ?arg arg ...? Option and the args determine the exact behavior of the command. The following commands are possible for database objects: dbName destroy Destroys the database object. dbName add user pwd storage Add a new user or changes the data of an existing user. Stores password and storage reference for the given user. dbName remove user Removes the specified user from the database. dbName rename user newName Changes the name of the specified user to newName. dbName lookup user Searches the database for the specified user and returns a two-element list containing the associated password and storage refer- ence, in this order. Throws an error if the user could not be found. This is the interface as expected by the authentication call- back of package pop3d. dbName exists user Returns true if the specified user is known to the database, else false. dbName who Returns a list of users known to the database. dbName save ?file? Saves the contents of the database into the given file. If the file is not specified the system will use the path last used in a call to dbName read. The generated file can be read by the read method. dbName read file Reads the specified file and adds the contained user definitions to the database. As the file is actually source'd a safe inter- preter is employed to safeguard against malicious code. This interpreter knows the add command for adding users and their associated data to this database. This command has the same argument signature as the method add. The path of the file is remembered internally so that it can be used in the next call of dbName save without an argument. BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category pop3d of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883]. Please also report any ideas for enhancements you may have for either package and/or documentation. KEYWORDS

pop3d::dbox(3tcl) Tcl POP3 Server Package pop3d::dbox(3tcl) __________________________________________________________________________________________________________________________________________________ NAME
pop3d::dbox - Simple mailbox database for pop3d SYNOPSIS
package require Tcl 8.3 package require pop3d::dbox ?1.0.2? ::pop3d::dbox::new ?dbName? dbName option ?arg arg ...? dbName destroy dbName base base dbName add mbox dbName remove mbox dbName move old new dbName list dbName exists mbox dbName locked mbox dbName lock mbox dbName unlock mbox dbName stat mbox dbName size mbox ?msgId? dbName dele mbox msgList storageCmd get mbox msgId _________________________________________________________________ DESCRIPTION
The package pop3d::dbox provides simple/basic mailbox management facilities. Each mailbox object manages a single base directory whose sub- directories represent the managed mailboxes. Mails in a mailbox are represented by files in a mailbox directory, where each of these files contains a single mail, both headers and body, in RFC 822 (http://www.rfc-editor.org/rfc/rfc822.txt) conformant format. Any mailbox object following the interface described below can be used in conjunction with the pop3 server core provided by the package pop3d. It is especially possible to directly use the objects created by this package in the storage callback of pop3 servers following the same interface as servers created by the package pop3d. ::pop3d::dbox::new ?dbName? This command creates a new database object with an associated global Tcl command whose name is dbName. The command dbName may be used to invoke various operations on the database. It has the following general form: dbName option ?arg arg ...? Option and the args determine the exact behavior of the command. The following commands are possible for database objects: dbName destroy Destroys the mailbox database and all transient data. The directory associated with the object is not destroyed. dbName base base Defines the base directory containing the mailboxes to manage. If this method is not called none of the following methods will work. dbName add mbox Adds a mailbox of name mbox to the database. The name must be a valid path component. dbName remove mbox Removes the mailbox specified through mbox, and the mails contained therein, from the database. This method will fail if the speci- fied mailbox is locked. dbName move old new Changes the name of the mailbox old to new. dbName list Returns a list containing the names of all mailboxes in the directory associated with the database. dbName exists mbox Returns true if the mailbox with name mbox exists in the database, or false if not. dbName locked mbox Checks if the mailbox specified through mbox is currently locked. dbName lock mbox This method locks the specified mailbox for use by a single connection to the server. This is necessary to prevent havoc if several connections to the same mailbox are open. The complementary method is unlock. The command will return true if the lock could be set successfully or false if not. dbName unlock mbox This is the complementary method to lock, it revokes the lock on the specified mailbox. dbName stat mbox Determines the number of messages in the specified mailbox and returns this number. This method fails if the mailbox mbox is not locked. dbName size mbox ?msgId? Determines the size of the message specified through its id in msgId, in bytes, and returns this number. The command will return the size of the whole maildrop if no message id was specified. If specified the msgId has to be in the range "1 ... [dbName stat]" or this call will fail. If stat was not called before this call, size will assume that there are zero messages in the mailbox. dbName dele mbox msgList Deletes the messages whose numeric ids are contained in the msgList from the mailbox specified via mbox. The msgList must not be empty or this call will fail. The numeric ids in msgList have to be in the range "1 ... [dbName stat]" or this call will fail. If stat was not called before this call, dele will assume that there are zero messages in the mailbox. storageCmd get mbox msgId Returns a handle for the specified message. This handle is a mime token following the interface described in the documentation of package mime. The token is read-only. In other words, the caller is allowed to do anything with the token except to modify it. The msgId has to be in the range "1 ... [dbName stat]" or this call will fail. If stat was not called before this call, get will assume that there are zero messages in the mailbox.
